The AB postcode hides the widest single spread in Scotland: lowland Aberdeen (Dyce) sits beside Braemar at 339m, one of the coldest places in Britain. A garden on the coast and one up in Deeside share a postcode but not a season.
Lowland frost here runs a little later than the Central Belt. Dyce's last frost is early May, and the uplands are among the latest anywhere in Scotland.
Where this covers
- AB Aberdeen, Aberdeenshire, Deeside, and Moray around Speyside, Keith and Buckie
Frost dates for Aberdeen & Aberdeenshire
- Lowland (coastal; under ~150m): last frost early May, first autumn frost late October, safe to plant out late May.
- Upland (Deeside and Cairngorm fringe; above ~150m): last frost late May to early June, first autumn frost mid-to-late September, safe to plant out mid June.
Dates are rounded to the nearest half month, from named Met Office stations (1991-2020 averages). Lowland means under about 150m; upland is above that.
| Garden | Last spring frost | First autumn frost | Safe to plant out | Season | Station | Confidence |
|---|---|---|---|---|---|---|
| lowland | early May | late October | late May | ~175 days | Dyce (Aberdeen) | high |
| upland | late May to early June | mid-to-late September | mid June | ~115 days | Braemar (339m) | high |
What this means for growing here
Sow and plant out to these dates rather than a UK calendar, and remember they are regional averages. Your own plot can run two to four weeks later in a frost pocket, or earlier against a warm wall. If your garden is above about 150m, use the upland figures; below that, the lowland ones. The Planting Calendar turns these into a month-by-month plan.
When to plant out tender crops here
Frost-tender crops go outside only once the safe planting-out date has passed, about two weeks after the last frost: late May on low ground and the coast, mid June on high ground in Aberdeen & Aberdeenshire. That applies to tomatoes, basil, cucumbers, sweetcorn, peppers, chillies and aubergines grown outdoors. That date is the earliest they can go out, not a promise they will ripen: on high ground only about 115 frost-free days follow it, so a greenhouse, polytunnel or cloches are the safer bet there.
